Answer:
A for 1 and 4 B for 2 and 3 ..........
Answer:
Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances. Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.
The red and blue will spread from the drops which will mix causing purple at the meeting and red pat that then over time it will spread to a murky purple
Explanation:
Mass ratio C : H : N = 27.3 : 9.10 : 63.6
Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14
( Divide the mass ratio by their molar masses to find the ratio between moles)
Mole ratio = 2.275 : 9.10 : 4.54
= 2.275/2.275 : 9.10/2.275 : 4.54/2.275
= 1 : 4 : 2
Answer is CH4N2
Answer:
B
Explanation:
The temperature is proportional to the kinetic energy of the system.
The kinetic energy is a measure of the movement capability of the molecules of the system. Hence, we can directly say molecules moving faster possess more average kinetic energy.
This kinetic energy is a measure of temperature. This is in the sense that the higher the temperature, the higher the degree of turbulnece . This tends to show us that the molecules are moving with greater speed.
Hence, we can conclude that there is a direct degree of proportionality between the temperature and the kinetic energy of the molecules as an increase in temperature causes a corresponding increase in the speed of the molecules
